Description

【0001】
【発明の属する技術分野】
本発明は、天井の裏側空間に設けた給気チャンバー内に発生する渦流によって吹出し風量が減少するのを防止するようにした空調用天井吹出口に関する。
【0002】
【従来の技術】
近年では、図2に示すように吊天井方式とした天井1の裏側空間P全体を給気チャンバー2とし、該給気チャンバー2に供給された調和空気を天井1に形成した吹出口3から室内4に吹出すようにした空調システムがある。この場合、上記給気チャンバー2が全体的に加圧された状態で空気が流通される。また、上記吹出口3の天井1裏側には、目隠しや消音のために覆い板5が設けられたり、図示は省略したが側面が開口された箱体が取付けられたりする。
【0003】
【発明が解決しようとする課題】
しかしながら、かかる従来の天井裏を給気チャンバーとした空調システムにあっては、天井1の裏側空間Pにおいて、吹出口3を中心とする渦流が発生する場合がある。
【0004】
図3に示すように吹出口3に渦流S(図中破線で示す)が発生すると、当該吹出口3付近の静圧が低下する。このとき、吹出口3からの調和空気の吹出量は減少し、設定された吹出量が得られなくなってしまう。このため、設定風量を確保するために、他の吹出口3も含めて全般的に風量調整する作業を要し、煩雑な手間が必要になってしまうという課題があった。
【0005】
そこで、本発明はかかる従来の課題に鑑みて、静圧低下の原因となる渦流が吹出口部分で発生するのを防止することにより、設定風量を確保して煩雑な風量調整を無くすようにした空調用天井吹出口を提供することを目的とする。
【0006】
【課題を解決するための手段】
かかる目的を達成するために本発明の空調用天井吹出口は、天井の裏側空間を給気チャンバーとし、天井に形成した吹出口から調和空気を吹出すようにした空調システムにおいて、上記吹出口の天井裏側周縁部に、該吹出口の中心から放射状に1枚または複数枚の整流板を取付けることにより構成する。
【0007】
以上の構成により本発明にあっては、吹出口の天井裏側周縁部に取付けた整流板が抵抗となって、該吹出口部分における渦流の生成を妨げることができる。このとき、上記整流板は渦流生成を妨げ得るに必要な所定高さに形成される。従って、上記吹出口部分で静圧の低下原因となる渦流生成を防止できるため、当該吹出口からの吹出量の低下を防ぐことができる。
【0008】
【発明の実施の形態】
以下、本発明の実施形態を添付図面を参照して詳細に説明する。図1は本発明の空調用天井吹出口の一実施形態を示す斜視図である。
【0009】
即ち、本実施形態の空調用天井吹出口は従来に示したと同様に、天井10と上階の床スラブ12との間の天井裏空間Pが給気チャンバー14として構成され、この給気チャンバー14に図外の空調装置から調和空気が加圧状態で送られる。一方、天井1には適宜箇所に環状の吹出口16が形成され、該吹出口16から上記給気チャンバー14内の調和空気が、圧力差により室内18に吹出すことにより天井吹出し式の空調システムが構成される。
【0010】
ここで、本実施形態では上記吹出口16の天井裏側周縁部に、該吹出口16の中心から放射状に4枚の整流板24,24…が設けられ、これら整流板24,24…は、それぞれの中心側が上記筒体20の外周に固定されるようになっている。
【0011】
以上の構成により本実施形態の空調用天井吹出口は、吹出口16の天井裏側周縁部に4枚の整流板24,24…を放射状に取付けたので、該吹出口16部分に渦流Sが発生しようとすると、取付けた整流板24,24…が抵抗となって過流Sの生成を妨げることができる。このとき、上記整流板24,24…の高さ方向の幅wは、渦流Sの生成を妨げるに必要な所定高さに形成される。従って、上記吹出口16部分において静圧の低下原因となる渦流Sの生成を防止できる。このため、当該吹出口16からの吹出量の低下を防ぐことができる。従って、吹出量を調整するという煩雑な作業を不要とできる。
【0012】
ところで、本実施形態では上記整流板24,24…を4枚設けた場合を開示したが、これに限ることなく1〜3枚若しくは5枚以上を放射状に設けることによっても渦流S発生を阻止できる。
【0013】
【発明の効果】
以上説明したように本発明の空調用天井吹出口にあっては、吹出口の天井裏側周縁部に取付けた整流板が抵抗となって、該吹出口部分における過流の生成を阻止することができるため、当該吹出口部分の渦流発生による静圧低下を防止して、当該吹出口からの吹出量の低下を防ぐことができる。従って、煩雑な吹出量の調整作業を省略することができるという優れた効果を奏する。

BACKGROUND OF THE INVENTION
The present invention relates to a ceiling air outlet for air conditioning in which the amount of blown air is prevented from decreasing due to a vortex generated in an air supply chamber provided in a space behind the ceiling.
[0002]
[Prior art]
In recent years, as shown in FIG. 2, the entire back side space P of the ceiling 1 having a suspended ceiling system is used as an air supply chamber 2, and the conditioned air supplied to the air supply chamber 2 is passed through the air outlet 3 formed in the ceiling 1. There is an air conditioning system that blows out to No.4. In this case, air is circulated in a state where the air supply chamber 2 is entirely pressurized. Further, a cover plate 5 is provided on the back side of the ceiling 1 of the air outlet 3 for blinding or silencing, or a box having an open side is attached although not shown.
[0003]
[Problems to be solved by the invention]
However, in such an air conditioning system in which the back of the ceiling is an air supply chamber, a vortex around the air outlet 3 may occur in the back space P of the ceiling 1.
[0004]
As shown in FIG. 3, when a vortex S (indicated by a broken line in the figure) is generated at the air outlet 3, the static pressure near the air outlet 3 decreases. At this time, the amount of conditioned air discharged from the air outlet 3 decreases, and the set amount of air can no longer be obtained. For this reason, in order to ensure setting air volume, the work which adjusts air volume generally also including the other blower outlet 3 was required, and there existed a subject that a troublesome effort would be needed.
[0005]
Therefore, in view of the conventional problems, the present invention prevents a vortex that causes a decrease in static pressure from occurring at the outlet, thereby ensuring a set air volume and eliminating complicated air volume adjustments. The purpose is to provide a ceiling outlet for air conditioning.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the ceiling air outlet for air conditioning according to the present invention is an air conditioning system in which the space behind the ceiling is an air supply chamber and conditioned air is blown from the air outlet formed in the ceiling. It is configured by attaching one or a plurality of rectifying plates radially from the center of the air outlet to the ceiling back side peripheral edge.
[0007]
With the above configuration, in the present invention, the rectifying plate attached to the ceiling back side peripheral portion of the air outlet becomes a resistance, and the generation of vortex flow at the air outlet portion can be prevented. At this time, the rectifying plate is formed at a predetermined height necessary to prevent vortex generation. Therefore, since eddy current generation that causes a decrease in static pressure can be prevented at the air outlet portion, it is possible to prevent a reduction in the amount of air blown from the air outlet.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing an embodiment of an air conditioning ceiling outlet according to the present invention.
[0009]
That is, in the ceiling air outlet for air conditioning of the present embodiment, the ceiling back space P between the ceiling 10 and the floor slab 12 on the upper floor is configured as an air supply chamber 14 as shown in the related art. The conditioned air is sent in a pressurized state from an air conditioner not shown. On the other hand, an annular air outlet 16 is formed at an appropriate location on the ceiling 1, and the conditioned air in the air supply chamber 14 is blown out from the air outlet 16 into the room 18 due to a pressure difference. Is configured.
[0010]
Here, in this embodiment, four rectifying plates 24, 24... Are provided radially from the center of the outlet 16 on the peripheral edge of the ceiling back side of the outlet 16, and these rectifying plates 24, 24. Is fixed to the outer periphery of the cylindrical body 20.
[0011]
With the above configuration, the air conditioning ceiling outlet of the present embodiment has four rectifying plates 24, 24,... Attached radially to the peripheral edge on the ceiling back side of the outlet 16, so that a vortex S is generated at the outlet 16 portion. If it tries to do, the attached current plate 24,24 ... will become resistance, and the production | generation of the overflow S can be prevented. At this time, the width w in the height direction of the rectifying plates 24, 24... Is formed to a predetermined height necessary to prevent the generation of the vortex S. Therefore, it is possible to prevent the generation of the vortex S that causes the static pressure to decrease at the outlet 16 portion. For this reason, the fall of the amount of blowing from the said blower outlet 16 can be prevented. Therefore, the complicated work of adjusting the blowout amount can be eliminated.
[0012]
By the way, although this embodiment disclosed the case where four said baffle plates 24, 24 ... were provided, it is not restricted to this, Generation | occurrence | production of eddy current S can also be prevented by providing 1-3 or 5 or more radially. .
[0013]
【The invention's effect】
As described above, in the ceiling air outlet for air conditioning of the present invention, the rectifying plate attached to the ceiling back side peripheral portion of the air outlet becomes a resistance, and the generation of overflow at the air outlet portion can be prevented. Therefore, it is possible to prevent a decrease in the static pressure due to the vortex generation at the outlet portion, and to prevent a reduction in the amount of blowout from the outlet. Therefore, there is an excellent effect that it is possible to omit complicated adjustment work of the blowout amount.
